✦ Synopsis

Opticlllly detected spin locking and adiabatic dcmngnetization in the rotating frame are used to dire& measure the rate constants for trap-to-band promotion and trap-to-trap energy nzigrafiolr in 1,2,4,5-tctrnchlorobcnzenc.

Comparison of these rate constants st 3 given temperature gives the quantum yietd for the decay of a promoted localized state into a mobile csciton state. Its dependcncc on temperature is also determined.
